MOLD OR IDIE FOR HEEL-COMPRESSING MACHINES.

SPECIFICATION forming part of Letters Patent N0..*776,860, dated December 6, 1904..

Application filed July 13, 1904. Serial No. 216,368- (No model.)

To all wit/mt it 771/1117 concern:

Be it known that I, THOMAS LUND, a subject of the King of Great Britain, residing at VVinchester, in the county of Middlesex and Com- 5 monwealth of Massachusetts, have invented certain Improvements in Molds or Dies for Heel-Compressing Machines, of which the following description, in connection with theaccompanying drawings, is a specification, like I reference characters on the drawings indicating like parts in the several figures.

This invention relates tocompressing-dies; and the object of the invention is to provide improved dies for compressing heels, and par- I ticularly to provide improved means for forming a heel having a rounded corner or edge at the junction of its seat and breast.

In the heel-compressing dies in general use the follower or die which acts upon the seat 2 face of the heel is provided with a lip for forming a bevel in the breast end of the seat of the heel. If the heel were not formed with this bevel, the portion of the heel that is to be removed by the breasting operation would cut 5 into the shank portion of the sole in the attaching operation and make an indentation which would detract greatly from the appearance of the shoe when finished. The bevel has been formed in the seat of the heel in an attempt 3 to obviate such defacement of the sole; but this expedient has not'been satisfactory, as will now be explained.

In heel-compressing machines heretofore used the presser-plate, which acts upon the tread-face, the breastplate, which acts upon the breast, and the radiall y-1noving dies, which act upon the sides of the heel, are usually mounted on a cross-head, said cross-head and the follower or heel-seat die being movable 4 relatively to each other in the operation of the dies for compressing a heel, and -as the follower is of the same size and outline as the seat of theheel after it is compressed the end face of the lip on the follower and the acting face of the breastplate pass each other in a substantially shearing action when the dies are brought together. It is practically impossible in machines of this character to keep the acting face of the breastplate in exact alinement with the end face of the lip on the 5 follower, and a space is accordingly formed between these two faces into which some of the leather in the heel flows, thereby forming a roughened projection on the upper edge of the breast of the heel at its junction with the beveled portion of the seat. A heel having a roughened projection of this character is almost as objectionable as one in which the breast end of the seat has not been beveled, because when the heel is being attached the roughened projection will cut into the shank portion of the sole and make an-indentation which will show plainly after the heel has been breasted. To prevent such a roughened projection from forming on the upper edge 5 of the breast of a heel during the compressing operation, I have devised OOIIIDIGSSIUgdies comprising a follower provided with means for rounding the upper edge of the breast of a heel, and cooperating with said 7 follower is a movable breastplate for molding the breast-face of the heel. Preferably the follower is provided with connected engaging faces for acting upon the seat, a portion of the breast, and the upper edge of the breast of the heel, and the movable breastplate acts upon the remaining portion of the breast and is yieldingly sustained in position with relation to the dies which act upon the sides of the heel.

Referring to the drawings, Figure 1 is a perspective view of compressing-dies which represent the preferred form of my invention. Fig. 2 is a detail perspective view showing the relative position of the follower and breast 8 5 plate when the dies are closed. Fig. 3 is a sectional view of the follower. Fig. I is a sectionalview of the presser-plate, radially-moving dies, and breastplate and shows a heelblank in position to be operated upon by the 9 follower. Fig. 5 is a view, partly in section, of a portion of a heel that was formed in my improved dies; and Fig. 6 is aview, partly in section, of a portion of a heel that was formed in dies such as have heretofore been in common use.

In the preferred form of my invention, as herein shown and described, the follower 1 is provided with an engaging face 2 for molding the seat-face 5 of a heel and is also provided with a lip 3 for forming a bevel 4 in the breast end of said seat, as shown in Fig. 5. Projecting downwardly from the breast end of the follower is an extended part 6, having an engaging face for acting upon a portion of the breast 9 of the heel, and said engaging face is connected with the engaging face of the lip 3 by a curved surface 8, which rounds the edge or corner 7, formed by the junction of the breast with the beveled portion of the seat of the heel.

The presser-plate 10, which acts upon the tread-face, and the radially-moving dies 12, which act upon the sides of the heel, are carried by a cross-head 1 1, on which a breastplate block 16 is mounted, said block having a guideway in which the breastplate 18 is movabl y mounted. The breastplate is mounted in alinement with the extended part of the follower and is normally held in the position shown in Figs. 1 and 4, with its upper end flush with the upper end of the breastplateblock, by means of a spring 20, said spring being connected at one end by a screw 22 to the breastplate and at the other end by a screw 2 1 to the breastplate-block.

During the first part of the compressing operation the entire breast-face of the heel is engaged by the breastplate 18, which is then in its elevated position, as shown in Fig. 4; but before the compressing operation is completed said breastplate will be engaged by the extended part 6 of the follower, and thereafter said breastplate will yield relatively to the dies which act upon the sides of the heel, so that the engaging face of said extended part can act upon the upper portion of the breast of the heel. The lip 3 on the follower forms a bevel in the breast end of the seat of the heel, and as the engaging face of said lip curves downwardly and merges into the engaging face of the extended part 6 the surface of the beveled and rounded portion in the end of the seat of the heel will merge into the breast-face of the heel.

A roughened projection, such as shown at 28 in Fig. 6, could not possibly form on a heel compressed in dies of the character herein shown, because the follower is providedv with connected engaging faces for acting upon the seat, a portion of the breast of the heel, and the corner or edge formed by the junction of these two faces. Such dies, moreover, can

be used for a longer period than dies in which there is a shearing action between the breastplate and the end face of the lip on the follower, as such an action causes these faces to wear rapidly.
